IMPROVEMENT IN TOOTH-BRUSH.

The Schedule referred to in these Letters Patent and making part of the same.

To all when it may concern Be it known that I, It. K. CHANDLER, of Ruther Glenn, in the county of Caroline, and State of Virginia, have invented a new and useful Improvement in Tooth-Brushes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanyingdrawings, making part of this specification, in Whlul1-- Figurel is a perspective view of my improved toothbrush.

Figure 2 is a side view of the brush, and a section through its handle.

Figure 3 is a sectional view of a removable hollow handle, and a side view of the brush.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to prevent fluid dentrifices from running upon the hands from the brush, while cleaning the teeth. 7

It consists in making that portion of the handle of a tooth-brush which is grasped in the hand while using such brush, hollow, and constructing that end of the hollow port-ion nearest the brush so that the fluids which run from the latter, while it is in the mouth, will be conducted into or through the said hollow portion, instead of upon its exterior surface.

' The following description will enable others skilled in the art to fully understand my invention.

In the accompanying drawings- A represents the handle of the brush;

B, the brush back, into which the bristles c are secured; and

a is the narrow or reduced shank of ,the brush-back.

The parts A, B, and a may be made of one piece of ivory, bone, hardened rubber, or of any other suitable substance suitable for tooth-brushes; or, if dc sired, the brush-back B, and its shank a, may be made separate from the handle A,- as shown in fig. 3, and secured to it by insertipgthereduced shank into the, end of the handle.

A brush-handle made detachable from the brushback would last for a great length of time, for when the brush proper is worn out, the part B can be detached from its handle, and a new brush inserted in its place.

The handle A is constructed hollow, the passage 1) extending through it from end to end, as shown in figs.

2 and 3, and that end of the handle nearest the brush c is made flaring or funnel-shaped, as shown at e, for

the purpose ofreceiviug the'fluids which run from the brush along the shank a, and conducting them into thepassage b.

It will be seen, by reference to figs. 1 and2, that. the shank a joins the handle at or near the centre of the concavity e consequently, fluids from the brush cannot run upon any side of its handle, but will all be. collected by said concavity, and caused to flow into the passage b.

If desirable, that end of the hollow handle A furthest from the brush may be provided with a stopple, for collecting the fluids in the handle during the act of cleansing the teeth. Then, by removing the stopple and pouring a little water through the handle, the passage b can be cleaned out or, if desirable, the passage may be left open at both ends, and the fluid from the brush allowed to flow freely through it while using the brush in the mouth.

It will be seen, from the above description, that I so improve the handle of, or for tooth-brush, that during the act of cleansing the teeth, water or the fluid dentifrices used on the brush will not run upon the ex terior surface of its handle, nor upon the hands.

Having described my invention,

What I claim as new, and desire to secure/by Letters Patent, is-

A tubular or hollow tooth-brush handle having a concavity, b, in one end, and forming a permanent or detachable part of the back of the brush, substantially as described and shown.
